Vehicle Sensing: 10 Technologies to Measure Traffic

23/03/2021· The piezoelectric sensor is mounted in a groove cut into road's surface. When a car drives over the piezoelectric sensor, it squeezes it and causes an electric potential - a voltage signal. The size of the signal is proportional to the degree of deformation. When the car moves off, the voltage reverses.
